- Behavioral: low-intensity intervention for anxiety
- Registration Number
- NCT05398016
- Lead Sponsor
- University of Nevada, Las Vegas
- Brief Summary
This single-arm pilot clinical trial will evaluate the feasibility, acceptability, and engagement of target mechanism, and preliminary impact of a low-intensity behavioral intervention for mild-to-moderate anxiety disorders. Treatment will delivered by trained lay counselors (n = 5) to patient participants (n = 15).
- Detailed Description
Anxiety is the most common adult mental health condition. Left untreated, it is costly and imparts significant personal and public health burden. Evidence-based psychotherapy (EBP) is an acceptable and effective first-line treatment; however, rural, low-income, and other underserved areas suffer from provider shortages, rendering such treatment largely unavailable. International contexts are beginning to address this problem using provider task sharing, in which low-intensity behavioral health services are delivered by non-specialist health workers (i.e., those with no prior training as a mental health professional). This approach is designed to improve access to care, particularly for those with mild-to-moderate symptoms, and free up limited expert resources. What is lacking is a brief, evidence-based, low-intensity behavioral intervention for mild-to-moderate anxiety disorders as well as an implementation blueprint (e.g., identifying appropriate clinical setting, stakeholder needs, supervision requirements, other counselor and clinic supports) needed to successfully implement and sustain such a novel service model in U.S. contexts. This study will begin to address the above problem in two phases, while creating the foundation for a longterm research program and external funding applications. The primary objective of this work is to develop and preliminarily test a brief intervention for anxiety appropriate for primary care and other non-specialty contexts. Investigators will test the intervention and delivery method via a small, single-arm pilot clinical trial. Non-specialists will be five undergraduate students, each working with three patient participants with anxiety (N = 15) to provide preliminary data on fidelity, feasibility, acceptability, preliminary clinical outcomes, and engagement of the target clinical mechanism of avoidance. The activities of these aims will develop community and clinical partnerships for testing and future implementation of low-intensity treatment paradigms.

Group Intervention Description Low-intensity behavioral intervention low-intensity intervention for anxiety Brief behavioral intervention for mild-to-moderate symptoms of anxiety. Delivered by a trained lay counselor.
- Primary Outcome Measures
Name Time Method Acceptability of Intervention Measure (AIM) Post-implementation (up to 1 year) Self-report measure assessing perceived acceptability of the intervention (an implementation outcome). Scores range from 4-20; higher scores indicate a higher degree of perceived acceptability. Completed by the trained lay counselors.
Feasibility of Intervention Measure (FIM) Post-implementation (up to 1 year) Self-report measure assessing perceived feasibility of the intervention (an implementation outcome). Scores range from 4-20; higher scores indicate a higher degree of perceived feasibility. Completed by the trained lay counselors.
Implementation Appropriateness Measure (IAM) Post-implementation (up to 1 year) Self-report measure assessing perceived appropriateness of the intervention (an implementation outcome). Scores range from 4-20; higher scores indicate a higher degree of perceived appropriateness. Completed by the trained lay counselors.
Number of patient participants retained in the intervention (out of all of those enrolled), as measured by completion to all study treatment visits. through treatment completion, up to 12 weeks Retention of patient participants will be measured as an implementation outcome. This will entail quantifying the number of patients who complete the entire course of treatment out of all of those enrolled.
Change in anxiety symptoms change in anxiety between pre- and post-treatment (6 weeks) (Patient outcome) Change between pre- and post-treatment will be assessed using the Structured Interview Guide for the Hamilton Anxiety Scale. This is a clinician-rated measure consisting of 14 items, each defined by a series of symptoms, to measure both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Total summary score ranges from 0 to 56, with higher scores indicating more severe and frequent symptoms of anxiety. A corresponding interview guide will be used to increase the reliability of the Hamilton Anxiety Scale. This measure has demonstrated sensitivity to change in clinical trials.
Change in avoidance change in avoidance between pre- and post-treatment (6 weeks) (Patient outcome) Change in avoidance will be measured using the Multidimensional Experiential Avoidance Questionnaire (MEAQ). This is a 62-item self report assessment of avoidance. Total scores range from 62 to 372; higher scores reflect higher levels of avoidance. This will be used to measure activation of target mechanism of avoidance.
- Secondary Outcome Measures
Name Time Method Change in anxiety symptoms (using Beck Anxiety Inventory) change in anxiety between pre- and post-treatment (6 weeks) Change in anxiety will also be measured using the Beck Anxiety Inventory (BAI). This is 21-question multiple-choice self-report inventory to measure the severity of anxiety of adults. Total scores range from 0 to 63, with higher scores indicating more severe and frequent symptoms of anxiety.
World Health Organization's Disability Assessment Schedule 2.0 (WHODAS 2.0) change in functioning between pre- and post-treatment (6 weeks) This 12-item generic health-status measure assesses functioning across six domains: communication, mobility, self-care, interpersonal, life activities, and participation. Item scores (0 = no difficulty to 4 = extreme difficulty or cannot do) are summed, with higher scores representing greater disability.
